An attempt was made to establish an SCID-hu murine model of long-term human hematopoiesis by coimplantation of a bone fragment and bone marrow (BM) cells from an adult human. The SCID-hu mice were treated with a cytokine mixture (recombinant human stem cell factor, interleukin-3, granulocyte/macrophage colony-stimulating factor, and granulocyte colony-stimulating factor) for 4 months and were t...

Macrophage-colony stimulating factor (M-CSF) has well-known effects on murine bone marrow, but its colony stimulating activity for human bone marrow is controversial. After treatment of human bone marrow with L-phenylalanine methylester (PME), macrophage-colonies (CFU-M) were induced by M-CSF in a dose-dependent fashion. The optimal concentration of recombinant human-macrophage colony stimulati...

two dogs with generalized seizures were evaluated. the dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (mri) of the brain. treatment was started with oxygen, prednisolone and anticonvulsant agents. no further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...

background: there are many reports regarding to effects of granulocyte colony-stimulating factor (g-csf) and stem cell factor (scf)alone in liver repair .but conflicting data have been reported regarding the role of growth factors such as g-csf and scf in the liver regeneration system. also, there is not such data regarding to effects of co-administration both of g-csf and scf in the liver dama...

Zinc finger proteins are transcriptional regulators of other genes, often controlling developmental cascades of gene expression. A recently cloned zinc finger gene, MZF-1, was found to be preferentially expressed in myeloid cells. Using complementary radiolabeled MZF-1 RNA hybridized to human bone marrow smears in situ, it was discovered that the expression of MZF-1 is essentially limited to th...

hematopoietic stem/progenitor cells (hspcs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. interacting factors such as stromal derived factor-1/cxcr4, very late antigen-4/vascular cell adhesion molecule-1, lymphocyte function-associated antigen-1/ intercellular adhesion molec...

Neutropenia and febrile neutropenia are two major complications of chemotherapy. Dose reductions, delays in treatment administration, and the use of granulocyte colony-stimulating factors are equally recommended options to preserve absolute neutrophil count in case of chemotherapy regimens bringing a risk of febrile neutropenia of 20% or higher. Recombinant granulocyte colony-stimulating factor...

Supernatants of cultured human thymic nonlymphoid cells were assayed for granulopoietic factors using cultures of low density bone marrow mononuclear cells (LD-BMMC). Thymic nonlymphoid cell-conditioned medium (TNLC-CM) supported vigorous myeloid colony growth of LD-BMMC. and of LD-BMMC depleted of T lymphocytes and/or monocytes. Colony stimulating activity (CSA) in TNLC-CM was abrogated by a h...

Maitake beta-glucan (MBG) is an extract from the fruit body of the Grifola frondosa mushroom that is being widely used to treat cancer in Asia. We have previously reported that MBG enhances mouse bone marrow cell (BMC) hematopoiesis in vitro and protects BMC from doxorubicin (DOX) toxicity. In the current study, we investigated the ability of MBG to enhance hematopoiesis and to reduce the toxic...
